Yellow-throated Fulvetta

An uncommon migrant songbird through Taiwan, rarely encountered anywhere away from breeding grounds on Izu and Tokara Islands, Japan. Olive above and whitish below; best distinguished from similar species by narrow bill with yellowish lower mandible, brownish-pink legs, and weak head pattern. Prefers mature coastal broadleaf forests but uses bamboo patches and conifers during migration as well. Smaller than Eastern Crowned Leaf Warbler, with thinner bill and no crown stripe. Song consists of a series of trills; calls, given often, include a descending “twee” or quiet “pee.”

A fairly small bird of wooded areas on the Bay Islands. Low crest is flattened at the front and rounded at the back. Male is glossy black with a purplish-blue iridescence. Female is medium gray above, pale gray below with brownish flight feathers and a darker mask, contrasting with the pale throat. Male similar to male Shining Flycatcher, but Biak is found in forest rather than waterside thickets and is smaller and less glossy. Often found in pairs and female has gray rather than rufous upperparts. Voice, a simple up-and-down whistled song and raspy call.

A large, slender warbler with a disproportionately long bill, short wings, and a long tail. Face and eyebrow yellowish-buff with a dark eye-stripe and a pale throat. Upper body and wings mostly dark with pale edges to feathers, giving a messy mottled appearance. Some birds are much paler, often almost entirely white with some mottling. An entirely dark sooty morph occurs. Found in riverine and hillside forest with stands of bamboo up to 600 meters of elevation. Song is a long, slow sequence of warbled phrases and “churr” notes. Calls include harsh churring and “tchak” notes.
